Vertical Representation of C∞-words
2015
International audience; We present a new framework for dealing with C∞-words, based on their left and right frontiers. Thisallows us to give a compact representation of them, and to describe the set of C∞-words throughan infinite directed acyclic graph G. This graph is defined by a map acting on the frontiers ofC∞-words. We show that this map can be defined recursively and with no explicit reference toC∞-words. We then show that some important conjectures on C∞-words follow from analogousstatements on the structure of the graph G.

Whose business is it anyway? Distributing responsibilities between family members and formal carers
2015
This study reports on a discourse analysis of how responsibilities for the care of older people are defined and distributed in the interview talk of working caregivers in Finland. The analysis focuses on how the interviewees depict their encounters with professionals (e.g. social and health care workers) and the responsibilities attached to the position of a family member versus professional. The theme is examined against the backdrop of broader Finnish and European discussions about the development of welfare society, the relations between the state and individual citizens as well as discussions about older people’s care needs. Data were obtained by face-to-face interviews. In the intervie…
Language ideological landscapes for students in university language policies: inclusion, exclusion, or hierarchy
2022
Many universities in non-English speaking countries have been adopting English as a medium of instruction to internationalize their education. We set out to compare the language policies of a Finnish and a Japanese university using the lens of language ideology – a set of normative beliefs about the social dimension of language. Data were collected from selected documents of the two universities, and analyzed utilizing critical discursive psychology. This social constructionist approach allows mapping out language ideological landscapes – interrelationships among different co-occurring language ideologies – from which students may draw ideas about how they orient themselves towards their pe…
Les éditorialistes : auteurs scientifiques ou acteurs sociaux
2007
Les éditoriaux peuvent être perçus comme une interface entre la recherche scientifique et l'opinion publique. Nous avons cherché à savoir si l'objectif des éditorialistes scientifiques n'est que de poursuivre une tradition journalistique, ou de mettre en œuvre des stratégies idéologiques ou sociétales, justifiant ainsi leur raison d'être dans la société au sens large. Cette étude présente les thèmes sélectionnés dans deux revues médicales britanniques de grande réputation sur une période de deux ans, ainsi que les liens potentiels avec les articles de recherche publiés dans les mêmes journaux scientifiques. Le but et l'utilisation même des éditoriaux sont analysés tant à l'intérieur qu'à l'…
Discovery-learning in grammar education:a study on anaphoric pronouns
2022
En les darreres dècades, en el context educatiu portuguès, com en altres països, la gramàtica ha estat un tema central de debat en l’educació L1. L’any 2001, amb la publicació del Currículum Nacional d’Educació Bàsica, la gramàtica, que es va anomenar «coneixement explícit de la llengua», es va considerar un dels components bàsics del currículum de L1 portuguès. Des d’aquesta perspectiva, inspirada en les propostes del moviment anglosaxó de consciència lingüística, l’objectiu principal de l’educació gramatical és desenvolupar els coneixements implícits que els infants ja tenen i utilitzen en un coneixement cada cop més reflexiu i explícit. En aquesta concepció, en què se suposa que «la majo…
Approcher les discours spécialisés par la méta-catégorie du figement
2018
Doctoral; Cet atelier doctoral, qui capitalise sur la présentation « Quelles approches cognitives pour les discours spécialisés ? » vise à discuter la pertinence pour l’approche des discours spécialisés de la notion de « figement », dans une acception cognitive large, détachée des conceptions traditionnelles de « figement morpho-syntaxique ». En faisant un détour par le cas très particulier de gestion du figement dans les langues contrôlées, on pose comme hypothèse l’existence d’un continuum à rebours invitant à partir précisément du figement - envisagé comme stabilité quantitative et reproductible - pour analyser ces discours. La deuxième partie discute les apports respectifs des tradition…
Explicit Recursive and Adaptive Filtering in Reproducing Kernel Hilbert Spaces
2014
This brief presents a methodology to develop recursive filters in reproducing kernel Hilbert spaces. Unlike previous approaches that exploit the kernel trick on filtered and then mapped samples, we explicitly define the model recursivity in the Hilbert space. For that, we exploit some properties of functional analysis and recursive computation of dot products without the need of preimaging or a training dataset. We illustrate the feasibility of the methodology in the particular case of the $\gamma$ -filter, which is an infinite impulse response filter with controlled stability and memory depth. Different algorithmic formulations emerge from the signal model. Experiments in chaotic and elect…
A fast recursive algorithm for the computation of axial moments
2002
This paper describes a fast algorithm to compute local axial moments used for the detection of objects of interest in images. The basic idea is grounded on the elimination of redundant operations while computing axial moments for two neighboring angles of orientation. The main result is that the complexity of recursive computation of axial moments becomes independent of the total number of computed moments in a given point, i.e. it is of the order O(N) where N is the data size. This result is of great importance in computer vision since many feature extraction methods are based on the computation of axial moments. The experimental results confirm the time complexity and accuracy predicted b…
Explicit recursivity into reproducing kernel Hilbert spaces
2011
This paper presents a methodology to develop recursive filters in reproducing kernel Hilbert spaces (RKHS). Unlike previous approaches that exploit the kernel trick on filtered and then mapped samples, we explicitly define model recursivity in the Hilbert space. The method exploits some properties of functional analysis and recursive computation of dot products without the need of pre-imaging. We illustrate the feasibility of the methodology in the particular case of the gamma-filter, an infinite impulse response (IIR) filter with controlled stability and memory depth. Different algorithmic formulations emerge from the signal model. Experiments in chaotic and electroencephalographic time se…
